At Mehra we are huge fans of Vass shoes out of Budapest. A fully hand welted made to order shoe available to customize in a huge variety of models, lasts, and leathers for $650 (including shoe trees) is surely one of the best values in the sartorial footwear world.
Vass uses only the finest leathers but their museum calf in particular really stands out. A defining feature of the museum calf used by Vass is the very subtle mottling effect. Not overwhelming or flashy but just subtle enough to give the leather some extra character.
Shown here is an Austerity Brogue in Gold Museum Calf on the U last.
